Shenhai Explosion-Proof
As technology advances, LED lighting has become increasingly prevalent, with a growing demand for LED explosion-proof lights in industrial lighting. LED explosion-proof lights offer numerous advantages such as energy efficiency and environmental friendliness. However, if you visit related electromechanical markets, you’ll find that most LED explosion-proof lights are low-priced and of inferior quality. To the untrained eye, these products may seem indistinguishable from standard LED explosion-proof lights. Understanding certain professional knowledge is essential. Here, I will introduce the acceptance criteria for LED explosion-proof lights, enabling you to truly understand and easily identify their quality.
Acceptance Criteria:
1. Identification:
LED explosion-proof lights should have a nameplate with the EX mark, type of explosion-proof electrical equipment, protection level, and temperature group. The label should also indicate the explosion-proof certification number issued by the inspection unit.
2. Compliance:
The protection level, temperature group, environmental conditions, and special markings of the LED explosion-proof light must comply with regulations.
3. Integrity of the Casing:
The casing of the LED explosion-proof light should be free from cracks or damage, the paint intact, and all parts securely fixed, including bolts and anti-loosening devices.
4. Lighting System Stability:
The lighting system of the explosion-proof light should be stable, with correct connections, and inlet and outlet installation positions should meet requirements.
5. Electrical Ingress Sealing:
Redundant electrical entries of the explosion-proof light should be sealed as required.
6. Circuit and Sealing Installation:
The installation of the LED explosion-proof light’s circuit or sealing device should be carried out according to regulations.
7. Wiring Verification:
The wiring of the LED explosion-proof light should be correct, and the routing and elevation should meet design requirements, with the line marked with a sky-blue symbol.
8. Grounding and Anti-Static Requirements:
Grounding or neutralization, and anti-static grounding of the LED explosion-proof light should meet design requirements and be firmly reliable.
